George A .D'Aguin ATTORNEYS Patented May 20, 1947 UNITED STATES PATENTorrlce 2 Claims.

This invention relates to a water purifier and it is one object of theinvention to provide an apparatus of this character by means of whichsea water may be purified and rendered fit for drinking.

Another object of the invention is to provide the apparatus with aboiler having a heater of improved construction mounted therein andcarried by a door which is movable outwardly to an opened position andcarries the heater with it so that cleaning and repairs may be readilyperformed.

Another object of the invention is to so form and mount the heater thata supply of fuel may be set in place therein without opening the doorcarrying the heater.

Another object of the invention is to provide the heater with an outletfor vapor having a guard of special construction which serves veryeffectively to prevent water from passing out with the steam or vaporduring operation of the apparatus.

Another object of the invention is to provide an apparatus of thischaracter wherein water may be pumped into the boiler and also to acondenser as means for converting the steam into water.

Another object of the invention is to provide a water purifier which isof light weight and quite small and compact, thus permitting it to beused in a life boat or raft and easily carried ashore after a landinghas been made.

The invention is illustrated in the accompanying drawings wherein Figure1 is a view showing the improved water purifier partially in verticalsection and partially in elevation.

Figure 2 is a sectional view upon an enlarged scale taken verticallythrough the boiler.

Figure 3 is a sectional view taken transversely through the boiler.

This improved water purifier has a boiler I which may be of anydimension desired but is preferably of such size that it can beconveniently placed in a life boat and carried ashore for use byoccupants of the boat after reaching land if necessary. The boiler hasan opening at one side which is normally closed by a door or closure 2having water tight engagement with walls of the Side opening 3. While asuitable number of bolts 4 have been shown as means for holding the doorclosed and forming a tight seal about margins of the door it will beunderstood that other means may be used.

Within the boiler is a fire box 5 which is formed of metal and isdisposed vertically in the boiler. Walls of the fire box are corrugatedcircumferentially to permit expansion and contraction and in order tosupport the fire box therehave been provided brackets 6 and 1 whichproject from the inner surface of the door and are secured against thetop and the bottom of the fire box inv transverse spaced relation to.each other. .By so mounting the firebox it will be carried by the doorand when the door is opened the fire box will be shifted out of theboiler to a position in which it can be easily cleaned or repaired, Theneck 8 extends laterally from the fire box so that a package of fuel 9may be thrust into the fire box and set inthe pocket or seat In of thebottom H. thereof and. in order to normally close the neck there hasbeen provided a door l2 having a damper l3 for controlling flow of airinto the firebox. A flue I4 extends upwardly from the center of the topl5 of th fire box and outwardly through the door 2 with its outerportion directed upwardly and carrying a damper l6 for controlling flowof products of combustion through the flue.

The boiler is filled with water which is forced into the same from apump I! through a pipe I8 and a checkvvalve l9 which opens in thedirection of the boiler and the extent of the opening of which isregulated and controlled by a screw Illa. The pump may be of any desiredconstruction and has an inlet hose or flexible pipe 20' of suflicientlength to be dropped over the side of a boat and into the ocean or otherbody of water on which the life boat is floating. A water gauge 2| isprovided for determining the depth of water in the boiler. As the wateris converted into steam or vapor it rises in the boiler to the topthereof and in order that danger or damage by an explosion be preventedthere have been provided a pressure gauge 22 and a safety valve 23. Thesteam or vapor passes out of the boiler through a flue 24 controlled bya valve 25 and in order to prevent too rapid movement of steam throughthis flue there hav been provided bafiie plates 26 disposed at anincline and extending in opposite directions in overlapping relation toeach Other. Each baffle plate 26 is provided near its lower end with adrain opening 26a. A cylindrical guard 21 controls fiow of steam intothe flue and is disposed horizontally in the upper portion of the boilerwhere it is secured by hanger bolts or rods 28 with its upstanding neck29 registering with the inlet of valve 25. Perforations 30 are formed inthe upper portion of the guard and from an inspection of Figure 1 itwill be seen that the steam must rise over the guard before it can enterthe same through the perforations. By providing drain openings 3| at thebottom of the guard, any condensation within the guard will return tothe boiler.

The steam or vapor which reaches to the top of flue flows through a pipe32 and through the depending end portion thereof into a condenser 33.This condenser is of cylindrical formation and extends horizontally withits discharge pipe extending downwardly from its bottom and connectedwith a chemical water sweetener 35 through which the water passes beforeit is delivered into a water receptacle 36. Cooling water flows throughtubes 31 of the condenser and out through a discharge pipe 38 having aglobe valve 39. In order to supply cooling water to the condenser therehas been provided a pipe 49 leading from the pipe l8 at a point betweenthe pump 11 and the check valve I9. When the valve 39 is choked down orclosed and the pump I! is in operation, there will be built up in thesalt water side of the condenser a pressure greater than that in theboiler, whereby to permit water to be fed to the boiler. When the valve39 is opened the water will flow freely through the condenser, with theresult that the vapor entering the condenser will be condensed and flowfrom the condenser into the sweetener and from the sweetener into thefresh water receptacle.

Having thus described the invention, what is claimed is:

1. A boiler for a water purifying apparatus having a side opening, aclosure for the side opening movable into and out of closed relationthereto, a fire box carried by said closure and disposed within saidboiler when the closure is in closing relation to the side opening, saidfire box having a neck registering with an opening in the closure forinsertion of a heating medium into the fire box, the bottom of the firebox being formed with a pocket to receive the heating medium, a flueextending upwardly from the fire box and out through the closure, a flueon said boiler, a valve in said flue controlling the emission of steamfrom said boiler through said flue, a conduit leading from the top ofthe flue for delivering vapor exteriorly of said boiler, and a pump forsupplying water directly to the boiler. 2. A boiler for a waterpurifying apparatus disposed vertically and having a side opening, aclosure for the side opening removably held in closing relation thereto,a fire box disposed vertically in said boiler when the closure is in itsnormally closed position, brackets carried by said closure andprojecting from the inner face thereof and secured to the top and thebottom of the fire box for supporting the fire box and withdrawing thefire box from the boiler when the closure is opened, a flue on saidboiler, a valve in said flue for controlling the emission of steam fromsaid boiler, bailie plates in said flue, a conduit for delivering vaporfrom the flue exteriorly thereof, and a pump for supplying Waterdirectly to the boiler.
